Bug: Failed to identify embeded citation keys of natbib

[syrte]

adstex (search_keys?) failed to identify Diemer2018 as a citation in the following example:

\citet[with implementation by \citealt{Diemer2018}]{watson13}

Right, adstex does ignore anything between the brackets of a cite command. I'll give it some thoughts but I am not sure if I'll be able to find a way around this as the regular expression is already quite complex at this point.

Alternatively, you can change the tex source to the following for adstex to detect both citations.

\citeauthor{watson13} (\citeyear{watson13}, with implementation by \citealt{Diemer2018})

Thanks for the workaround.
Sure, I guess this is only an uncommon edge case in practice.
